76718-05-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 76718-05-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,7,1 and 8 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 76718-05:
(7*7)+(6*6)+(5*7)+(4*1)+(3*8)+(2*0)+(1*5)=153
153 % 10 = 3
So 76718-05-3 is a valid CAS Registry Number.

Fabrycy, Andrzej,Wichert, Zofia
, p. 1744 - 1750 (2007/10/02)
The unknown 3-benzoylmethylene-2,3-dihydrofurans 2 has been synthesized by isomerization of ditertiary diacetylenediols 1 in the presence of mercury salts.Sometimes carbocyanine type dyes 5 are formed as by-products.
